In a Mobile Wireless Sensor Network (MWSN), mobile sensor nodes move freely at the network environment. So, a large number of attacks threaten this network. Unauthenticated broadcast attack is a common attack which worsens the network congestion as well as energy consumption. In this paper, an efficient method for defending unauthenticated broadcast ATTAcks (AT2A) in MWSN has been proposed. AT2A method keeps sending history of each node in transmission table of nodes to make decision about each incoming packet, i.e., packet should be dropped or forwarded.
